Abstract: Some embodiments of the present invention provide a snow plow blade gate apparatus and method in which the gate is pivotably attached to an end of a snow plow blade. The gate can be pivotable between a deployed position in which the gate blocks snow from exiting the snow plow blade to a stowed position in which at least part of the gate is moved to a location behind the snow plow blade. In some embodiments, the gate pivots about an axis skewed with respect to a substantially vertical plane. Also, some embodiments of the present invention have an actuator that can be actuated to secure the gate in a deployed position.

Abstract: An apparatus and a method for removing snow from a travel surface, including a wear member movably connected to a main blade or wing blade. In some embodiments, a fastener connected to the wear member extends through an aperture in the blade and is biased in a downward direction by a biasing mechanism connected to the blade. The biasing mechanism can include a spring, brackets retaining the spring in position with respect to the blade, and a shaft connected to the fastener and to the spring to exert a biasing force (e.g., a downward force) upon the fastener and therefore upon the wear member. The wear member can pivot about a pivot point while the biasing member biases the wear member against the travel surface.

Abstract: An apparatus and a method for removing snow, including a conveyor mounted at an angle with respect to a travel direction of the apparatus. The conveyor is rotatably mounted to a frame and can be driven to throw snow laterally with respect to a travel direction of the vehicle to which the apparatus is mounted.

Abstract: A snowplow mountable on a track or similar vehicle includes a displaceable trip edge that enables the plow to pass over trip hazards without transferring significant impact forces to the plow. The plow mold board includes one or more trip plates that are coupled to the mold board through compression spring elements and linkages. The linkages cause the trip edge to swing up and away from the pavement to avoid "undercutting" when a trip hazard is encountered. This helps keep the plow from jumping. The linkage also automatically reduces the moment arm defined by the compression spring element, the trip plate and the mold board so as substantially to compensate for an increasing restoring force generated by the compression spring member as it is progressively compressed. The trip plate can thereby be displaced over its entire range without significantly increasing the contact force between the trip plate and an encountered trip hazard.
